Audiobook Player

Audiobook Player is a simple, focused player for your own audiobook collection — whether it lives on your device or on your Synology NAS.

This is an early version and I'm improving it constantly. I'm a solo developer, so your feedback reaches me directly. If something is missing or broken, please email me from Settings before leaving a rating; I usually fix things fast.

Key Features:

Local Files — Play M4B audiobooks straight from your device storage. No account, no internet required.

Synology NAS — Add your own Synology NAS as a source, browse your audiobooks, and download them to your device to listen offline. Your files stay yours. Connect over HTTPS, or use Synology QuickConnect.

Android Auto — Listen in the car. Browse your recent audiobooks on your car's screen, with chapter controls and cover art on the now-playing view. Plays books that are on your device (local or downloaded).

Remembers Your Place — The app automatically saves your position in every book. Pick up exactly where you left off, every time.

Chapter Navigation — Jump between chapters with ease. The full chapter list is always one tap away.

Sleep Timer — Set a timer to stop playback after 15, 30, or 60 minutes.

Playback Speed — Adjust speed from 0.75× to 2× to match your listening style.

Clean Interface — A distraction-free UI focused entirely on your listening experience.

Note: This app plays your own legally acquired audiobook files. It does not sell or provide audiobook content.

Coming soon: MP3 support and remote streaming.
